No sound issues on TVs are typically easy to fix. If the problem isn’t due to hardware failure and you can see the picture but not hear the sound on your TV, you can fix it yourself. Most sound problems are resolved in minutes, whether it’s a Samsung, Sony, LG, Vizio, or other TV brands.
You can see the picture but not hear it even if your TV isn’t mute. It might not be a mute issue but rather a lack of other settings or hardware functionality.
You can find the picture visibility but the absence of sound problem in practically all televisions, and it is usually an easy fix.
Make sure to troubleshoot the problem with multiple steps before seeking professional help.
The most common cause is a change in your TV’s settings or a loose or disconnected cable, which results in a sudden loss of sound but still allows you to view the picture on the screen.
Reasons for TV’s No Sound
When you hear no sound but see an image on your TV, it could be for various reasons. You can experience this with any TV brand, including LG, Vizio, Sony, TCL, Insignia, Hisense, Sharp, Philips, Panasonic, Toshiba, Sanyo, etc.
You can quickly find a remedy if you know what is causing the problem.
The most challenging element of a remedy is identifying the problem’s fundamental cause; after you’ve done that, there’s not much else to do.
There are various reasons why your TV may stop playing sound, including incorrect settings or the inappropriate HDMI input:
• The volume of your TV or external speakers is very low or muted.
• Sound settings are incorrect.
• Incorrectly connected external speakers or soundbars.
• Media devices that aren’t connected to the TV, such as the receiver, DVD player, or gaming console, due to unhooked connections, ports, or incorrect settings.
• Failure of the TV’s internal components, external speaker, or media devices due to hardware failure.
• It’s possible that a reset is on the way.
• The Secondary Audio Protocol is enabled on your TV.
• The audio input on the TV is changed, for example, to AUX.
• There’s a chance the channel you’re watching right now doesn’t have audio.
• Your television may be equipped with a headphone jack.
• It’s possible that a connection cable has become loose or disconnected.
• The built-in speakers on your TV have been damaged.
• The mainboard may be damaged.
• Signal Source may be damaged.
• TV software is out of date.
• Your TV’s settings have become corrupted.
Fixes For No sound on TV
Here are a few things to look for to see if you can fix the problem and get your TV sound back.
1. Double-check the mute switch
Mute can completely turn off the sound on your TV. As a result, it’s critical to double-check this setting.
Someone other than you may have silenced the sound, and you may be unaware of it.
Even if you verified it previously, we recommend doing so again before proceeding.
2. Increase the volume
No sound will come from the TV if the volume is zero or very low.
Check the volume of your TV speakers, and if you’re using external TV speakers, make sure they’re loud.
3. Restart the TV
To maintain running correctly, all gears must be rebooted over time. Rebooting any electrical equipment acts as a minor reset and cures various issues.
You should also try turning off your TV and any other connected gadgets. If there is a momentary issue, a reboot may be all that is required to resolve it.
4. Verify if there is a secondary audio protocol
If you set your TV to Secondary Audio Protocol, you won’t get any sound through the speakers (SAP).
As a result, make sure to double-check this setting as well.
5. Audio Input Settings on the Television
You or anyone else who has access to your TV’s remote control may change the audio input by accident, and you are unaware of it.
If someone with the TV remote hits the “AUX” button, it will set the audio input to AUX, but no such device will be attached.
In this situation, the audio will play through the device that is not connected to the TV.
So make sure you’re using the correct input method.
6. Change the TV channel
There are instances when there is a transmission problem, and you cannot hear sound from a specific channel.
It is not a problem on your end. You should experiment with different channels to see if you can receive sound.
If you don’t hear sound on any channel, there could be a problem on your end.
7. Examine the Headphone Port
Your TV may connect to headphones that aren’t visible to your eyes. Check to see if the headphone jack is empty and not plugged in.
The headphone jack is usually located in front of your TV.
8. Examine the connection cables
When plugging or disconnecting, the connecting cables can become somewhat slack or separated.
It’s also conceivable that you repositioned the TV, causing the cords to loosen. As a result, there may be no sound, and you will only see the image.
It’s an excellent idea to re-plug all connecting cables to ensure they’re correctly linked.
If you notice any damage to a cable, replace it with a new one.
9. Restore Factory Settings (Factory Reset)
Changes in settings can result in many issues, especially when you alter settings that you are unaware of; you disrupt the device’s functionality without even knowing you’re the cause of it.
We frequently change things, just like we do with television, even though we don’t have complete information about them. The best way to get your TV’s factory settings is to restore it to its default settings.
This reset may wipe all of your data, but it is the only way to ensure that all of your settings are correct.
The reset helps to solve the problem in some cases. If the problem remains, you can go to the following step knowing that the settings are correct.
After pressing and holding the menu button for 10 seconds, the restore tab will appear. Then, to complete the reset, follow the on-screen instructions.
The restoration procedure will differ depending on the model and brand of your TV.
10. Make sure your TV software is up to date
The sound on a few or all channels can be affected by outdated software or drivers.
Check which software version your TV is currently running. In this scenario, a TV handbook might be instrumental.
Check to see if there are any software updates available. You should install an update as soon as possible if an update is available.
The software can be updated automatically if your TV is connected to the internet. You can also manually update it using a USB disk.
11. Verify with external speakers
Connect an external audio device, such as a receiver, surround sound, or any other device that can play audio to see if the TV is transmitting sound.
Check to see if the audio is audible through external speakers.
12. Examine the signal source for any damage
Weak signal strength is another crucial factor that might result in “No sound.” The signal must have a strength of at least 20db.
You can verify your signal by heading into your TV’s Settings. Ensure that Self-diagnosis, Open Help, and Signal Information are all available.
13. Check HDMI cable and port
Faulty HDMI cable and port can ruin your whole TV experience. You have to confirm that your HDMI and your TV’s HDMI port are working perfectly, and if not, you can buy a replacement cable and get your HDMI port fixed.
What if your TV doesn’t have HDMI? Here’s what you can do.
Why does my TV suddenly have no sound?
Check your TV’s and linked devices’ audio settings. Turn off and unplug your TV and any other gadgets connected to it. Examine the TV cables and ports, then do the same with the cables and ports on your gadgets. Replace the media device or switch the TV’s speaker output to the internal speakers to see if the sound improves.
How do I get the sound back on my LG TV?

Why has the sound gone on my LG TV?
First, make sure the TV isn’t muted or turned down. We propose that you experiment with various sound sources, not only live television, such as Netflix, Prime Video, Youtube, or your gaming console and DVD. ‘AV reset’ is a good option.
These are some of the possible remedies for a TV with no sound. Any of these options will work well for you, and you will be able to restore your TV sound as quickly as possible.
